A nurse is assisting with the admission of a client who has a subarachnoid hemorrhage and increased intracranial pressure (ICP). Which of the following medications should the nurse anticipate the provider prescribing to decrease ICP?
Nicardipine
Phenytoin
Dopamine
Mannitol
The Correct Answer is D
A. Nicardipine is a calcium channel blocker primarily used to manage blood pressure but does not directly reduce ICP.
B. Phenytoin is an anticonvulsant used to prevent seizures, which may occur after a hemorrhage, but it does not address increased ICP.
C. Dopamine is used to increase blood pressure and cardiac output but does not play a role in reducing ICP.
D. Mannitol is an osmotic diuretic that helps decrease ICP by drawing fluid from brain tissue into the bloodstream, thus relieving pressure within the skull. It is the most appropriate intervention for managing increased ICP.
